Zebra
Finch
FAMILY:
Estrildidae
GENUS: Poephila
SPECIES: guttata
OTHER
NAMES: Chestnut-eared Finch.
Description:
Medium
sized finch with distinct plumage. Head and back grey grey-brown, chestnut ear
patches. Throat, neck and upper breast pale grey with fine black bars. Lower
breast has broad black bar. Flanks dark chestnut with white spots. Tail coverts
barred in black and white. The legs are orange, eyes and bill red.
Females
resemble males but lack the chestnut colouring and black barring on the breast.
Throat, breast and underparts are pale buff and the bill is paler. Immature
birds are dull versions of females with black bills and grey eyes, legs and
feet.
One of the most common and widespread of the Australian finches, the
Zebra Finch is sedentary and lives permanently in flocks. Non breeding flocks
usually number around 100, but during dry periods thousands of individuals may
congregate near water. Breeding colonies usually consist of somewhere around 25
pairs.
Zebra finches are mostly terrestrial in their feeding habits. Pair
bonds are thought to last for life.
Length:
100-110mm.
Subspecies:
The
nominate species P. g. guttata is found in Timor and surrounding
Indonesian islands. It differs from the Australian subspecies P. g.
castanotis in that it has the throat and upper breast pale grey with only
faint barring.
Status:
In
the wild - common
In
aviculture - common
Distribution:
Throughout
mainland Australia.
Habitat:
Most
types of dry grassland and agricultural lands.
Diet:
Seeds
and insects.
Breeding:
Opportunistic
and almost continuous. The breeding season is strongly influenced by rainfall.
In fact, Zebra Finches will begin courting and nesting just several hours after
rain.
The nest is flask shaped, 120-200mm in diameter, with an entrance
tunnel of around 80mm. Both parents build the nest which is constructed from
grass. Nests are most often located on twigs of bushes or low
trees.
In
captivity Zebra Finches will nest in virtually any receptacle on offer. Some
aviculturalists report Zebra Finches breeding in a cut down Coke can.
Courtship
Display:
Males
approach females in a pivoting dance accompanied by much hopping on the perch.
Feathers on the head and chest are ruffed and the tail twisted toward the
female. Many males also crow during this process. Females indicate their
receptiveness by tail quivering.
Sexual
Maturity:
Of
all the Australian finches these birds mature most rapidly, becoming sexually
mature about 9 weeks after hatching.
Clutch:
4-5
pure white eggs (15mm x 11mm). Incubation period: 12-14 days. The young usually
fledge at around 15-17 days. Fledged birds should not be removed from the
parents until at least 4 weeks after fledging.
In captivity, Zebra Finches
will produce many broods per season providing that plenty of nesting sites, seed
and live food is available.
Mutations
and Hybrids:
Zebra
Finches have hybridised with a number of species including: Black-throated
Finch, Chestnut-breasted Mannikin, Diamond Firetail, Double-barred Finch, Java
Sparrow, Long-tailed Finch, Masked Finch, Plum-headed Finch, Saint Helena
Waxbill, Star Finch African Silverbill,African Firefinch, Bengalese Finch,
Black-headed and Tri-coloured Mannekin.
Zebra Finches are perhaps the most
common aviary finch and have been held in captivity for a long time. This and
their propensity to breed has led to a large number of colour variations which
are too numerous to mention. The main forms are as follows: Grey, Fawn, White,
Grey Pied, White Pied, Silver and Cream.
Suitable
Aviaries and Compatible Birds
For
breeding purposes Zebra Finches will be quite happy in suspended cages or
breeding cabinets. These should have at least the following dimensions:
700mm(long) x 400mm x 400mm. These birds are at their best in larger planted
aviaries.
Zebra Finches will readily share an aviary with most other small
seed eaters (eg. zebra, painted, parrot, etc etc) including doves and quail. One
problem that aviculturalists experience with this species is that Zebras tend to
be very competitive for nesting sites and have been known to exclude other
species from nesting. On the other hand, one or two pairs of Zebras may induce
other species to breed.
